White-woolly throughout, stem simple, 6—18 inches high. Leaves spatulate to lanceolate or linear, 1—4 inches long, acute, nerved. Heads numerous in a close capitate cluster, ½—1 inch high, outer bracts of the involucre straw-colour or greenish, rounded and often notched at the apex; inner ones nearly white. In moist open ground in the Rockies at the lower elevations; flowering in July. [Sidenote: =Antennaria racemose= Hook. _White Everlasting._] Lightly woolly, becoming smooth, stems 6—20 inches high, slender, sparsely leafy. Leaves thin, the radicle broadly oval, an inch or two long, obscurely 3-nerved at the base, rather veiny, the lower stem leaves oblong, the upper smaller and lanceolate. Heads of flowers about ¼ of an inch high, all on slender peduncles in a loose raceme, involucral bracts, thin and translucent, greenish-yellow or brownish. On shaded slopes throughout the Rockies, at the higher altitudes; flowering in June. [Sidenote: =Antennaria Howellii= Greene. _Howell’s Everlasting._] More or less woolly; stem 6—10 inches high. Leaves rather thin, the lower spatulate, acute, 1—2 inches long, green above, woolly beneath; stem leaves lanceolate, clasping, 1 inch long, becoming smaller toward the summit. Heads in a compact capitate cluster, ½ an inch or more in diameter, woolly at the base; involucral bracts very narrow, acute, thin, and translucent, straw-colour, the outer ones densely woolly and occasionally rosy. In dry ground and on slopes, frequent in the Rockies at the lower altitudes. [Sidenote: =Antennaria parvifolia= Nutt. _Mountain Everlasting._] Plant silvery throughout, freely spreading; stems prostrate and leafy, forming mats of considerable extent; flowering stems 2—8 inches high. Leaves from obovate to spatulate, ½ an inch or less long, persistently white-woolly. Heads in compact terminal clusters about ⅓ of an inch broad; involucral bracts, lanceolate, obtuse, thin and translucent, yellowish. In dry sterile ground at the lower altitudes throughout the Rockies; flowering in June, frequently growing with the next species which it closely resembles in manner of growth. [Sidenote: =Antennaria rosea= (D. C. Eaton) Greene. _Pink Everlasting._] Silvery throughout, stems prostrate and leafy, forming broad mats; flowering stems 6—15 inches high. Leaves very thin in texture, densely hairy, lanceolate to linear, ½—1½ inches long, acute. Heads small, closely compacted into a rounded terminal cluster, ½ an inch or more in diameter; involucral bracts in 2 series, lanceolate, the outer greenish and woolly, the inner from pink to bright rose-colour. In dry sterile or moist open ground throughout the Rockies up to an elevation of 6,000 feet; flowering in June and July. [Sidenote: =Anaphalis subalpina= (A. Gray) Rydb. _Pearly Everlasting._]
